Green Ultrasound Assisted Synthesis of N2,N4,N6-tris ((Pyridin-2-ylamino) methyl)-1, 3,5-triazine-2,4,6-Triamine as Effective Corrosion Inhibitor for Mild Steel in 1 M Hydrochloric Acid Medium

摘要

An new corrosion inhibitor namely N N ,N -tris ((Pyridin-2-ylamino) methyl)-1, 3,5-triazine-2,4,6- triamine (INH) was synthesized using green ultrasound technique and its inhibition property oncorrosion of mild steel has been studied using gravimetric measurement, Potentiodynamicpolarization , electrochemical impedance spectroscopy (EIS) and linear polarization (LR) resistance .Potentiodynamic polarization measurements reveal that this compound effectively suppressedcorrosion of mild steel in acid solution and acts as mixed-type inhibitor. EIS plots indicates that theaddition of inhibitor increases the charge-transfer resistance (Rct) and decreases the double-layercapacitance (Cdl) of the corrosion process this reveals that investigated inhibitor inhibits mild steelcorrosion by adsorption on its surface. The adsorption of inhibitor on the mild steel surface obeysLangmuir adsorption isotherm.
